Claims.

This invention relates to a window ventilator and more particularly to awindow ventilator that may be mounted in a window that is alreadyinstalled.

Numerous types of window ventilators and inbuilt ventilators have beenused, some of which are adapted to be mounted in a section of a windowformerly closed by a window pane, illustrative of which is the devicedisclosed in my Patent No. 2,316,634 granted April 13, 1943, forVentilating Fan.

An object of this invention is to provide a window ventilator utilizingair propelling means that may be mounted in a portion of a double hungwindow.

Another object of this invention is to provide air circulating meansthat is mounted in an opening adapted to receive a window pane, the aircirculating means being provided with muntin means for supportingglazing in the portion of the window opening that is not covered by theair circulating means.

Another object of this invention is to provide air circulating meanshaving incorporated therein adjustable muntin sections adapted tosupport at least a portion of the air circulating means.

Another object of this invention is to provide air circulating meansthat utilizes standard parts adapted to accommodate various sizes ofwindow openings, resulting in a structure that is inexpensive, lendsitself to mass production and at the same time has sufiicientflexibility to accommodate various sizes and types of window openings.

Another object of this invention is to provide air circulating meansadapted for use with a selected set of muntin sections selected from aplurality of various sizes of sets of muntin sections, the sets beingselected to fit the particular window in which the air circulating meansis being mounted.

Other objects and advantages reside in the construction of parts, thecombination thereof and the mode of operation, as will become moreapparent from the following description.

The ventilating unit disclosed herein is adapted for use in windowsnormally having a glazing space much larger than the ventilating unit.It has been shown as used in connection with a conventional wooden sash,wherein the installation of the glazing unit has been accomplished byremoving a window pane, suspending the panel i! of the ventilating unitfrom the top rail member extending across the top of the window pane andsupporting the bottom of the ventilating unit by adjustably mountedmuntin sections having the ends attached to the sash stiles of thewindow. After the ventilating unit has been mounted in position, thespace below the ventilating unit is glazed by utilizing the adjustablemuntins and the bottom of the ventilating unit as the top muntin for theglazing. The spaces located on either side of the ventilating unit arealso glazed by using the glazing seats or rabbets of the ventilatingunit and the muntin sections as glass supports for two sides of eachglass-receiving space. The other two sides of the glazing is supportedby the top rail member and the side stiles of the window, as will appearmore fully from the description that follows.

Referring to the drawings, the reference numeral l0 indicates thevertical side stiles of a conventional wood sash. The reference numerall2 indicates the top rail member and I4 indicates the bottom railmember. The window frame or window sash may be any conventional window.In inserting the ventilating unit, the glazing is removed.

A ventilating unit panel 20, which may be made from suitable sheetmetal, is suspended from the top rail member l2. The panel 20 has anoffset flange 22 extending along the top, adapted to be seated in theconventional glazing seat of the top rail member [2. A pair of links 24are fixedly attached to the top rail member 12 by suitable screws 26.The lower ends of the links 24 each support a screw 28 passing throughthe panel 20 and held in adjusted position by a pair of nuts 38 and 32.This permits alignment of the panel with respect to the glazing seat, tothereby accommodate various thicknesses of mullion bars.

The panel 20 is provided with a large circular opening. A cylindricalshell 36 surrounds the circular opening and is provided with a flange 38welded or otherwise secured to the panel 20. The cylindrical shell 36 isenclosed by a housing 40 mounted on the outside of the opening. Thehousing 40 is provided with a closure 42 that may be opened in a mannersimilar to the ventilating fan assembly described in my Patent No.2,316,634 granted April 13, 1943.

The flange d4, surrounding the housing 48, rests upon an angle iron lfi,extending along three sides of the panel. The angle iron 46 cooperateswith the margin of the panel 29 to form glazing seats, as will bedescribed more fully later. The panel 20, the angle bar 45 and theflange Ml are welded together, or otherwise secured together, to form aunitary structure. The panel and the angle irons, together with thehousing 40, constitute a fixed assembly that may be used in variouswindow openings and suspended from the top mullion bar as disclosed. Theinside of the opening is covered by a suitable grill :56. The fan 52 ismounted in the housing and may be identical to the fan disclosed in myPatent No. 2,316,634.

As may best be seen by referring to Figure 5, the panel 28 is providedwith a deflected portion Gil supporting a downwardly projecting flange62 terminating in a reentrant flange 64, providing a housing fo the faceof the T-shaped muntin segments 66, there being one Of these segmentsadjustably mounted on either end of the panel 2!]. The segments 66 areselected to fit the particular width of window from a plurality ofsegments of various lengths. The stem of the T-bar 66 ispositionedbetween the flange of the angle bar 46 extending across thepanel 20 near its bottom anda plurality of clips '68 are held inposition by suitable screws is engaging L-shaped angle brackets 12. Thebrackets 12 are secured to the side of the upwardly directed flange ofthe angle bar 46 and held in position by screws [4. The screws Ed passthrough the panel 20, the flange of the angle bar 4,6, and threadedlyengage the L. -shaped angle brackets 12. The outer end of each of themuntin segments 55 has the cross bar severed to permit the portion 86 ofthe stem of the T-shaped bar to project beyond the cross bar, as bestseen in Figures 2 and 6. A pair of L-shaped brackets 82 are spot-weldedor otherwise secured to the portion 80 of the T-bar. The brackets 82 areprovided with apertures for receiving screws 84, securing the *muntinsegments to the sash stiles In.

In assembling the ventilating assembly in the window opening, theglazing, if the window is glazed, is first removed. The panel 20 isprojected into the glazing seat found in the top rail member l2. Thelinks 24 are then secured in position by the screws 26 entering thetoprail member 12. The nuts 30 and. ,32 are then adjusted,-so as toproperly position the panel-20 with respectto the rabbet or glazing seatin the top. ra l; member. I1 .Aft r the p her an .20 has been secured inposition and properly aligned, the muntin segments 66 are then adjustedin position by loosening the screws 10, permitting a sliding movement ofthe muntin bars with respect to the panel 20 to cause the L-shapedbrackets 82 to engage the sash stiles Ill. The screwst l are thenscrewed into position, so as to hold the muntin sections in the properposition. The screws 10 are then tightened, so as to rigidly clamp thebottom portion of the ventilating unit to the muntin segments 66. Assoon as this has been done, a suitable window pane is cut to fit theopening below the ventilating unit. It is held in position by suitableglazing points engaging the sash stiles l0 and the bottom rail member Mand puttied in position throughout the entire margin of the window pane90. A pair of window panes 92 are then cut to fit the openings betweenthe ventilating unit and the sash stiles ill and the muntin sections 66and the top rail gmember l2. After these window panes are secured inposition by suitable points and putty, the assembly of the panel withrespect to the sash is then complete.

The panel 2i} and its housing are preferably assembled without themotor, the fan and the grill being secured in position. After the paneland the parts associated therewith have been inserted and secured inposition, either before or after the glazing is completed, the fan, themotor and the parts associated therewith may be secured in position,together with the grill or guard extending across the opening.

The panel, the fan housing, the fan and the grill shown hereinconstitute a standard assembly that may he used in various sizes ofopenings, The muntin sections 56 permit limited adjustment in width.These sections are selected for the particular window from a pluralityof muntin sections of various lengths, so that a dealer or a contractormay stock the panels and the fan assemblies in readiness for use. Thedealer may also carry a suitable stockof various lengths of muntinsections, thereby providing ventilating units that may be used invarious sizes .of windows without the dealer carrying a stock ofcomplete units for eachsize of window, which would mean an excessivelyheavy inventory and undoubedly result in an over supply of somedimensions and a scarcit of others, depending uponthe requirements of aparticular community. By providing a standard assembly that may be usedin various sizes of windows, the inventory is greatly reduced.

Although the preferred embodimentof the device has been described, itwill be understood that within the purview ofthisinventionvariouschangesmay be; made in the form, details, proportion and arrangement ofparts, the combination thereof and-dnfideof operation, which generallystated consist in a device capable o f carrying out theobjects setforth, as disclosed and defined inthe appended claims.
